This is an activity about the tides. Learners discover how the Moon's gravitational pull causes the level of the ocean to rise and fall twice a day along most coastlines. Six children represent the oceans, solid Earth, Moon, and Sun and move their...(View More) bodies to show the interactions of these elements. They then consider what the Earth's tides might have been like if there were no Moon. They model the smaller tides that would be produced solely by the Sun. This activity is part of Explore! Marvel Moon.(View Less)

Learners use a Styrofoam ball, sunlight, and the motions of their bodies to model the Moon's phases outdoors. An extension is to have children predict future Moon phases. This activity is part of Explore! Marvel Moon.

This is an activity about the way the moon interacts with sunlight. Learners consider a ball, wrapped in aluminum foil, and experiment with a flashlight to make it appear bright. The children compare the foil-wrapped ball to a Moon globe and...(View More) discover that the Moon reflects very little of the light the falls on it, but still appears bright. The children construct their own globe of the Moon to take home with them by gluing a map template onto a tennis-ball. This activity is most effective when conducted in a dark area, such as outdoors at night or in a darkened room. This activity is part of Explore! Marvel Moon.(View Less)

This Science On a Sphere (SOS) module is designed to help the public better understand the story of water on Mars and how we're learning more about it. It portrays the mystery of what happened to the water on Mars in the context of a detective...(View More) story. NASA's MAVEN mission (Mars Atmosphere and Volatile EvolutoN) will help solve this mystery by studying the Martian atmosphere, how it has changed over time, and how it interacts with the Sun and the solar wind. The module also delves into Mars exploration, featuring past, present, and future Mars missions, and includes an activity comparing images of water-related features on Earth and Mars. It will help people understand that a planet's climate can change over time and how learning more about Mars helps us learn more about Earth and other planets as well. Resources included are: script, SOS playlist and datasets, background and tips for the docent or facilitator, and image comparisons of water-related features on Earth and Mars.(View Less)

Learners will construct a valid scientific question that can be answered by data and/or modeling and choose an appropriate mission for their rover that will answer their scientific question. The lesson uses the 5E instructional model and includes:...(View More) TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, four Vocabulary Cards, and supplements on writing a scientific question and possible Mission Choices. This is lesson 5 of the Mars Rover Celebration Unit, a six week long curriculum.(View Less)

In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that...(View More) emits energetic helium nuclei (alpha particles), e.g., the mineral the mineral autunite, which contains uranium. This is activity two of four from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER).(View Less)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters...(View More) can be determined using actual light curves from stellar occultation events. Includes adaptations for younger students and those with visual impairments.(View Less)

This is a lesson about water and water-ice. Learners will explore the molecular geometry and mechanics of ice. They will create a model of H2O, investigate its molecular structure and its consistent shape. Faraday's experiment is used as background....(View More) Activities include small group miming, speaking, drawing, and/or writing. This is lesson 2 of 12 in the unit, Exploring Ice in the Solar System.(View Less)

This is a lesson about the formation of glaciers, ice layering and stratigraphy, and the cryosphere and cryobotics. Learners will collect evidence of layering, explore the science story that layering tells, study snow and ice for insights into...(View More) climate change, and learn about the tools used to explore ice layers on Earth and in the solar system. Connections between rings of a tree and rings in an ice core will be made. Activities include small group miming, speaking, drawing, and/or writing. This is lesson 7 of 12 in the unit, Exploring Ice in the Solar System.(View Less)

This is a lesson about ice worlds in the outer planetary regions and the role they play in understanding the Solar System. Learners will role-play stories connecting science-related literature to ice worlds, view and interpret space-based images of...(View More) ice worlds, and investigate surface and interior features of outer planetary ice worlds. Photometry and spectroscopy will be used as background. Activities include small group miming, speaking, drawing, and/or writing. This is the lesson 11 of 12 in the unit, Exploring Ice in the Solar System.(View Less)
